DMPE Inc. New MK 8 LT Thunderbird Carbon Fiber Injector Hat
Darren Mayer Performance Engineering Inc. along with manufacturer C.G. Composites (England) are proud to announce the latest in Carbon Fiber Injector Hats the MK 8 LT.
The new MK 8 LT features new advances in air flow and proper port construction above the supercharger inlet port. Mayer explains, “It’s been a very exciting year to say the least. Development has been the forefront at DMPE in all regards. The new MK 8 LT moves our product line one step further forward. Carlo from C.G. Composite’s is a true craftsman and it really shows in this piece”.
The hat which features a 65 square inch blade opening, captured set back blades, spread front mounting points (for both air flow and for ease of mounting), and CAD designed inner radii to properly feed the supercharger inlet port. Bottom openings will range from 9 inches to 10.5 inches. Gandolfi’s states, “It’s actually simple thinking when it comes down to it. We want non-turbulent controlled air entering the rotor cavity. The way the air enters the passing rotor is the key, and when we improve the rotor fill we increase the engines horsepower potential.
The hat which has already gone into process is available immediately and exclusively through DMPE Inc.

DMPE Release's New Fuel Management Block
Darren Mayer Performance Engineering Inc. adds to its ever-growing list of specialty products by manufacturing the first modular designed fuel management jet and valve actuator system. Knowing that fine tuning is the difference between winning and losing, we have developed a fuel management system that can be tailored to your specific needs. This product was developed from tuning blown alcohol cars and the need to gain the most important competitive edge.
The new DMPE fuel management block is a modular design in which the racer can add more fuel management control as needed. The basic unit can be simple as a single controlled jet, and as your needs increase so can the amount of fuel management. Additional management sections can be inserted to expand the management log infinitely. While the norm is a three control log, we have demand for four and even five controlled jet systems, and now this is achievable with our cost effective fuel block system. Secondary to the control is the unit’s compact design. It has no bulky fittings or potential leaky manifolds. The DMPE unit requires one -6 line in and one -6 line out. We also have allowed provisions so it is possible for these lines to enter or exit from any side of the unit, to further add to ease of fit into today’s modern compact racing environments.
The DMPE modular management blocks are 3D designed and CNC machined to ensure exact fit and function required by today’s racers.

Trower Racing and DMPE Inc. to Continue in 2008
Trower Racing and D.M.P.E Inc. continue together in 2008.
The Professional A.S.D.R.A racing team of Rod and Dee Trower, based in Tonkawa, OK, will continue with two car team for 2008 under Darren Mayer’s watchful eye. An excited Rod Trower stated, “We enjoyed our first year of supercharged Sand Drag racing and look forward to picking up the pace in 2008. We have stepped my wife Dee's car up to a Billet Small Block Chevy with a 14-71 Kobelco Superman and Alan Johnson cylinder heads. My dragster will still sport its Fontana/Minor Brothers Hemi with a DMPE Inc prepared Kobelco Supercharger. The small block dragster combination has proven its ability by running mid 2.50's in Frank Martiscelli’s DMPE Inc prepared sand dragster in 2006. So it will be interesting to see if we can better those marks with Dee driving. The Fontana/Minor Brothers hemi has dropped a few high 2.50's but experienced mechanical issues during the 2007 season. We plan to use the winter to work out the problems this engine struggled with and possibly change to a design that will meet the call. Crew chief Darren Mayer has set a goal to run 2.40's. I’m just excited to be the guy that mashes the gas to see if we can achieve it”
After many season as an accomplished drag racing tuner on the asphalt, Darren Mayer has really enjoyed the challenge of racing on the sand. He exclaims, “I never really thought I would have ended up racing in the sand but it tests your ability to apply power without just digging a rut. I’ve learned a lot about these cars the past two years, and while we have won many of the races we have attended. I am yet to be satisfied with how any one pass has laid out. I’m looking forward to spending time on the dyno time with both engines and increase the team’s potential to win and run at the top. My goal is to run 2.40's with both cars this year and I think we can do it”.
Team Trower will get underway on their 2008 racing quest in Primm, Nevada on April 18-20 and continue through the year through November 8 in Atoka, OK.
Croker Blast's to New Record
Adam Croker, of Perth Western Australia, set a new standard for roots style blown alcohol dragsters at the first meeting of the ‘07-‘08 race season at the Kwinana Motorplex in W. Australia on November 3, 2007
Croker, who stepped away from Top Doorslammer racing for a year or two to concentrate on DMPE Down Under, smashed the previous AA/D record of 5.82 with a remarkable 5.67 @ 247 mph on just his second hit in the car. Croker stated, “I had no doubt that in time we could run very well but to do it as soon as we did, is what I’m so happy about. Darren and Jon from DMPE Inc. told me we had awesome power in my Doorslammer last year, but we just could not make smooth runs. I guess they were right! Now my team owns the title to the quickest and fastest roots powered alcohol dragster in the world”.
Croker unfortunately fell victim to parts attrition in the next round as the 2 step solenoid cracked a fitting and leaned the motor causing considerable damage. The disappointment was even greater when he found out that it was .05 faster to the 1/8 mile mark than the 5.67 run and the fitting broke at 800 ft. The team hopes to have the engine repaired in the next 3 weeks and be back on track and improving on the newly set record.
Croker Racing thanks the following companies for their support: Croker Construction, DMPE DU, R&R Contracting, Brooks Hire, N.K. Contractors, Mineral Transport and Link Low Loaders.

DMPE Inc Goes "Down Under"
DMPE Inc. of Stevensville, Michigan has opened its doors in Perth Australia. DMPE’s mission is to service the needs of the many supercharged methanol burning customers in the growing sport of drag racing in Australia. The obvious name of DMPE DU (Down Under) seemed appropriate for the adventure. Upon partnering with Adam Croker of Perth, WA the idea became a reality. In order to offer the Australian customers, the same quality of service and knowledge, it was in order to transplant Croker to the U.S. for training at DMPE Inc.
Croker, spent a month in Michigan at DMPE Inc, and has undergone complete training with respect to servicing and repair of roots style superchargers, fuel systems and ignitions. Croker states, “It was an intense undertaking to say the least. I wanted to come back to Australia with as much knowledge as possible. Darren and his great staff of employees have done a superb job teaching me all the vitals of proper servicing and repair to all types of roots superchargers and of course they are at my disposal if I ever need to be guided or assisted”.
Not only will DMPE Down Under provide the needed supercharger service and repairs but also offer a complete parts stocking list for blown alcohol racers. Mayer stated, “We have worked with Australian racers in the past and are aware of the difficulties they face receiving quality parts, service and technical knowledge. We have trained Adam on repairing, servicing and modifying all types of roots superchargers intensively. We even built the needed specialty tooling and shipped it all to Adam to ensure the work is identical in quality as received from DMPE Inc. in the U.S.A”.
DMPE DU will inventory items to assist racers needs and help reduce lead times on many desired parts. Items include NGK Spark Plugs, MSD Ignition, common ring and bearing packages, common rod and piston packages and much more.
DMPE DU will be based in Perth, WA, but will serve the entire country. For a complete list of parts and services please contact Adam Croker/DMPE DU at 0409-486-907 or email adam@dmpeinc.com

DMPE Inc. to Distribute C.G. Composites Carbon Fiber Injector Hats
Carlo Gandolfi, owner of C.G.Composites in Northants, England, is pleased to announce a new marketing and distributorship with Darren Mayer Performance Engineering Inc. of Stevensville, Michigan.
C.G. Composites is excited to have a reputable U.S. based company sell and stock the first and highest quality carbon fiber injector hats in the high performance racing market. Gandolfi states, "In previous years, Carbon By Design also know as Knut, sold my product. Times changed and we parted ways and I wish them well. With 90% of my customers based in the US, this partnership with DMPE Inc. is a natural progression".
Mayer, owner of DMPE Inc. exclaims, “The C.G. Composites product is second to none. Carlo is a true carbon fiber craftsman. This is a perfect compliment to my supercharger business. We are very anxious to start our marketing campaign together”.
Gandolfi's product, which was the first of it's kind, has graced more championship cars than any other brand since 1998. The signature three-blade carbon hat is used on roots style, supercharged cars in Top Fuel, Nitro Funny Car, and Pro Mod. There are also injector hats for screw compressor cars in NHRA alcohol classes and Outlaw Pro Mod.
We also ask that you accept no imitation of the original high quality C.G. Composites product. It is often confused with other brands on the market emulating the original by using lower quality materials and improper manufacturing techniques. For a complete guide to the C.G. Composites injector hat line please visit the Injector Hat section of our online store.

DMPE Inc. Supercharger Gel Lubricant
Darren Mayer Performance Engineering Inc. adds to its ever-growing list of specialty supercharger products by manufacturing the first specifically designed Supercharger Lubricant and Lubricant remover.
The DMPE Inc. Supercharger Gel Lube provides a better performing supercharger by addressing Teflon wear and leak path control. While extended Teflon / Nylatron wear through proper lubrication extends supercharger performance longevity,
the Gel’s ability to cling to the rotating rotors and internal parts also increases the efficiency of the unit by filling up the clearance between moving parts. It tightens the seal between rotor to rotor, and end frame to rotor clearance thus allowing the supercharger to increase efficiency by reducing leak paths. This also reduces costs by decreasing time between overhauls.
The gel lube is not affected by methanol like many supercharger lubes, therefore provides a better, longer lasting seal.
The Gel Lube Remover was specifically manufactured to remove the above lubricant. The lubricant was designed to hold up to most all solvents and methanol, allowing the lube not to be washed away from the rotors, rotor bores and internal supercharger surfaces.
Because of this it requires a “remover” to cut the supercharger gel at time of re-striping. It is important to remove all traces of the lube from the Teflon grooves so that the Teflon does not pitch itself out of the rotors after overhaul because of any remnants of the slippery lubricant.
Once all the rotor stripping is removed from the rotors, the dovetails should be sprayed with the remover to ensure removal of all gel lube. The Teflon is then pulled into clean dry grooves (dovetail) and the supercharger can then be re-assembled.
After the supercharger is re-assembled, liberally apply the supercharger lube into the rotor cavity. We suggest that it is applied once a day, usually on first start up. For more info and pricing please click HERE for Lubricant. Click HERE for
Lubricant Remover.

D.M.P.E Inc. Releases Popular Billet Injector Hat Spacer
Darren Mayer Performance Engineering has now officially released the first readily available Billet Aluminum Injector Hat spacer. The spacer is designed to direct air from the injector hat into the rotor cavity at the proper complimentary angle thus increasing rotor filling. The spacer is found to be beneficial when tall injectors are not applicable or impact air is desired to be drawn from the body
structure seen commonly in Pro-Mod and Funny Car applications.
Racetrack and dyno testing alike has proven the usefulness of this little the device to increase manifold pressure, useful horsepower and torque.
If your watching the Pro Mod’s racing on Sunday there is a good chance you should have bolted the power adding spacer on before you left home, the drive home would have been a lot more fun Sunday night.
The injector hat spacer is CNC machined from 6061-T6 Billet aluminum, has provisions for o-rings to ensure sealing to both the injector hat and the blower, if your blower does not have an o-ring provision.
The spacer is also designed to lock the mounting bolts in place to stop any bolts from coming loose, removing the possibility of damage to the supercharger.
